modified rankine
cycle basically same as rankine
cycle but main difference is inisentropic
expansion process.we
are nt
expanding the styeam
completely.steam is expanded up to certain level and after that it dumped in condenser
due to high vacuum in condenser.the
work losses by restricting the expansion
of steam is very less which can be neglected.so
that the stroke length of
cylinder is reduced and the capitalcost
of engine also reduced.engine
performance is also good
Rankine cycle allows for practical implementation with real working fluids such as water, making it more feasible for thermal power plants compared to the idealized Carnot cycle. Rankine cycle also allows for the use of turbines and pumps which are more efficient than isothermal expansion and compression processes in the Carnot cycle. Additionally, Rankine cycle can be modified with reheating and regeneration to improve efficiency further, something the Carnot cycle cannot achieve.
The Rankine cycle is important in thermodynamics because it is a theoretical model that represents the ideal process for converting heat into mechanical work in a power plant. The PV diagram of the Rankine cycle shows the stages of this energy conversion process, including heat input, expansion, heat rejection, and compression. By analyzing the PV diagram, engineers can optimize the efficiency of power plants by understanding how energy is transferred and transformed throughout the cycle.
To increase the efficiency of a Rankine cycle, you can: increase the boiler pressure to increase the temperature of the steam entering the turbine, lower the condenser pressure to improve the quality of the exhaust steam, and use regenerative feedwater heating to reduce heat losses. Additionally, using superheated steam can also improve the efficiency of the cycle.
A Rankine cycle diagram typically shows four main components: a boiler, a turbine, a condenser, and a pump. The process involves the heating of water in the boiler to produce steam, which then expands through the turbine to generate power. The steam is then condensed back into water in the condenser before being pumped back to the boiler to repeat the cycle.
27 degrees Celsius is equal to 497.67 degrees Rankine. You can convert Celsius to Rankine by adding 273.15 to the Celsius value and then multiplying by 9/5.
Thermal power station of 210mw will work on principle of modified Rankine cycle
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.

Rankine cycle is used in steam turbine
The Rankine cycle is the fundamental thermodynamic underpinning of the Steam_engine. It is named after William_John_Macquorn_Rankine
carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid rankine cycle is a practical cycle but with a very low efficiency so the main difference lies in the adding and rejecting of heat
The four major components of the rankine cycle are as follows: 1. boiler 2. turbine 3. condenser 4. pump i.e. in short (B-T-C-P)

The condenser is used to lower the temperature of the working fluid. This lowers the pressure and condensates any left over steam, from the turbine, so it will be purely liquid before entering the pump.
Rankine. Rankine is a temperature scale that is used alongside Fahrenheit, where 0 Rankine is absolute zero and each degree Rankine is equal to a degree Fahrenheit.
